Abstract
Description
Technical Field
[0001] The present application relates to the field of magnetic suspension compressors, and in particular to a magnetic suspension bearing controller. Background Art
[0002] The magnetic levitation motor uses core technologies such as magnetic levitation bearings, three-dimensional flow impellers, high-speed permanent magnet synchronous motors, high-efficiency inverter speed regulation, and intelligent monitoring and control. It suspends first and then rotates when starting, without friction or lubrication. The permanent magnet shaft is suspended by using the principle of "like repels like, opposites attract" between the motor stator and the permanent magnet shaft excitation magnetic field, and at the same time generates a propulsion force to drive the permanent magnet shaft to move in a suspended state.
[0003] The magnetic bearing controller can transmit the feedback information of the position and posture of the rotor detected by the sensor in real time to the electromagnet. The electromagnet will control the magnitude and direction of the current based on the feedback information, generate a magnetic force corresponding to the force on the rotor, and make the rotor suspend in a relatively stable position.
[0004] Nowadays, the heat dissipation method of most magnetic bearing controllers is to use a fully transparent structure inside the box, and then use a cooling fan to blow air to take the heat out of the box. The cooling fan is likely to blow a lot of dust into the box during the blowing process, and the internal cleanliness and dustproof effect is poor, affecting the service life of components such as the magnetic suspension drive board and magnetic suspension mainboard module inside the magnetic suspension bearing controller. In addition, the structure of most magnetic suspension bearing controllers is assembled by traditional sheet metal bending and forming structural accessories. There are many assembled parts, and the assembly method of parts is mainly based on single splicing assembly, which makes the internal structure of the magnetic suspension controller too complicated and the size of the magnetic suspension bearing controller too large, which is not conducive to installation and disassembly during maintenance. Summary of the invention
[0005] The purpose of the present application is to provide a magnetic bearing controller with a dual heat dissipation method, which can ensure the heat dissipation effect while keeping the interior clean and dust-proof, thereby increasing the service life of parts.

[0025] The present application provides a magnetic suspension bearing controller 100, including a housing 101, a magnetic suspension drive board 102, a drive board heat dissipation profile 103, an upper cover plate 104, at least one heat dissipation fan 105, a bottom sealing plate 106, a magnetic suspension mainboard module 107 and a power supply module 108, wherein the housing 101 is provided with a first opening and a second opening opposite to each other; the magnetic suspension drive board 102 and the drive board heat dissipation profile 103 are both arranged in the housing 101, the back side of the magnetic suspension drive board 102 is closely attached to the drive board heat dissipation profile 103, and the drive board heat dissipation profile 103 is closely attached to the housing 101; the upper cover plate 104, at least one heat dissipation fan 105, a bottom sealing plate 106, a magnetic suspension mainboard module 107 and a power supply module 108, wherein the housing 101 is provided with a first opening and a second opening opposite to each other; the magnetic suspension drive board 102 and the drive board heat dissipation profile 103 are both arranged in the housing 101, the back side of the magnetic suspension drive board 102 is closely attached to the drive board heat dissipation profile 103, and the drive board heat dissipation profile 103 is closely attached to the housing 101; The cover plate 104 is matched and installed in the first opening, and the upper cover plate 104 is provided with at least one cooling fan installation position, and the cooling fan 105 is installed in the cooling fan installation position; the bottom sealing plate 106 is matched and installed in the second opening, and the bottom sealing plate 106 is tightly arranged with the driving board heat dissipation profile 103, and the contact area between the bottom sealing plate 106 and the driving board heat dissipation profile 103 is provided with at least one cooling hole (not marked in the figure); the magnetic levitation mainboard module 107 is arranged above the magnetic levitation driving board 102; the power supply module 108 is arranged above the magnetic levitation mainboard module 107.
[0026] Compared with the prior art, the present application arranges the back of the magnetic levitation drive board 102 in close contact with the drive board heat dissipation profile 103, so that the heat of the magnetic levitation drive board 102 is transferred to the drive board heat dissipation profile 103, and at the same time, the drive board heat dissipation profile 103 is arranged in close contact with the shell 101, and the wide shell 101 can also take away some of the heat from the drive board heat dissipation profile 103. In addition, at least one cooling fan 105 is arranged on the upper cover plate 104, and the drive board heat dissipation profile 103 is arranged in close contact with the bottom sealing plate 106, and the bottom sealing plate 106 can also take away some of the heat from the drive board heat dissipation profile 103.

[0027] When the magnetic levitation controller starts to operate, the air blown by the cooling fan flows from the upper cover plate 104 to the bottom cover plate 106, so the air can blow the heat on the power module 108, the magnetic levitation main board module 107, the magnetic levitation drive board 102 and the drive board heat dissipation profile 103 out of the device through the heat dissipation holes on the bottom cover plate 106. The dual heat dissipation mode of air cooling and natural heat conduction of the drive board heat dissipation profile 103 ensures the heat dissipation effect while keeping the inside of the magnetic levitation controller clean and dustproof.
[0028] In addition, by disposing the magnetic levitation mainboard module 107 above the magnetic levitation drive board 102, and disposing the power supply module 108 above the magnetic levitation drive board 102, and by centrally and modularly arranging the positions of the internal components of each magnetic levitation controller, the internal layout structure of the magnetic levitation controller is compact, which can effectively solve the problem that the magnetic levitation controller is large in size and occupies a large space.
[0029] In one embodiment, the magnetic suspension bearing controller provided by the present application further includes a fixed column 109, a heat insulation board 110, a warning module 111 and a magnetic suspension network port board 112, wherein the magnetic suspension main board module 107 is arranged above the magnetic suspension drive board 102 through the fixed column 109, the heat insulation board 110 is arranged above the magnetic suspension main board module 107 through the fixed column 109, the power module 108 is fixed on the heat insulation board 110 and is closely arranged with the heat insulation board 110; the magnetic suspension network port board 112 is arranged between the magnetic suspension main board module 107 and the heat insulation board 110 through the fixed column 109, and the warning module 111 is installed on the magnetic suspension network port board 112 by pressing and fixing. By arranging the heat insulation board 110 and the power supply module 108 to be closely arranged, the heat insulation board 110 can take away part of the heat of the power supply module 108, thereby ensuring the heat dissipation effect of the power supply module 108.

[0030] In other embodiments, the magnetic levitation mainboard module 107 is suspended above the magnetic levitation driving board 102 through the fixed column 109, the thermal insulation board 110 is suspended above the magnetic levitation mainboard module 107 through the fixed column 109, and the magnetic levitation network port board 112 is suspended between the magnetic levitation mainboard module 107 and the thermal insulation board 110 through the fixed column 109. Through the suspension setting, there is a certain gap between the magnetic suspension mainboard module 107, the magnetic suspension drive board 102, the heat insulation board 110 and the magnetic suspension network port board 112, and the wind flow blown by the cooling fan 105 can pass through the gap, increasing the contact area between the wind and the magnetic suspension mainboard module 107, the magnetic suspension drive board 102, the heat insulation board 110 and the magnetic suspension network port board 112, so that the wind can take away more heat from the components such as the magnetic suspension mainboard module 107, the magnetic suspension drive board 102, the heat insulation board 110 and the magnetic suspension network port board 112, further improving the heat dissipation effect. Of course, according to actual needs, the suspension setting mode of the magnetic suspension mainboard module 107, the magnetic suspension drive board 102, the heat insulation board 110 and the magnetic suspension network port board 112 can be adaptively adjusted, for example, a multi-layer copper frame is set inside the magnetic suspension, and the internal components of the magnetic suspension controller are installed on each layer of the copper frame in turn.
[0031] In one embodiment, one end of the magnetic suspension network port plate 112, one end of the magnetic suspension mainboard module 107 and one end of the magnetic suspension drive plate 102 are all closely arranged with the bottom sealing plate 106, and the contact area between the bottom sealing plate 106 and the magnetic suspension network port plate 112, the magnetic suspension mainboard module 107 and the magnetic suspension drive plate 102 is respectively provided with at least one wiring through hole (not marked in the figure).

At least one heat dissipation through hole is provided in the non-contact area between the heat insulation board 110 and the power module 108, so that the airflow blown by the cooling fan 105 can pass through the heat dissipation through hole, thereby reducing the obstruction of the heat insulation board 110 to the air cooling of the components inside the magnetic levitation controller. Of course, according to actual needs, the shape of the heat insulation board 110 can be adaptively modified while avoiding the wiring area of the magnetic levitation mainboard 107.
